摘要

手术切除、放疗和化疗是全球治疗癌症的主要策略。然而,目前的治疗方法由于术后并发症和多种副作用给患者带来了新的疾病负担,特别是在口腔鳞状细胞癌(OSCC)等表面肿瘤中。在这项研究中,我们首次开发了一种微波冷大气等离子体(CAP)装置,该装置与肿瘤微环境响应纳米羟基磷灰石(nHA)结合使用。体外和体内实验评价了CAP和nHA联合应用对OSCC的协同作用。体外研究了CAP和ph响应性NH2-nHA对OSCC细胞凋亡、细胞内活性氧(ROS)和钙离子浓度的协同作用。CAP与NH2-nHA协同诱导对OSCC表现出最佳的肿瘤特异性抑制作用。结果表明,CAP与NH2-nHA联合应用可诱导体外肿瘤细胞凋亡,体内肿瘤杀伤率达84.0%。在机制上,CAP促进细胞外ROS的产生,而NH2-nHA增加细胞内钙离子(Ca2+)浓度,协同增加细胞内ROS水平,引起OSCC细胞氧化应激,最终触发线粒体凋亡途径。综上所述,CAP和NH2-nHA的联合应用作为一种新的、选择性的、非侵入性的OSCC治疗策略,具有广阔的前景。

Synergistical Induction of Apoptosis via Cold Atmospheric Plasma and Nanohydroxyapatite for Selective Inhibition of Oral Squamous Cell Carcinoma in Tumour Microenvironment.

Surgical resection, radiotherapy and chemotherapy are the primary strategies of treating cancers globally. However, the current treatment methods bring new disease burdens to patients due to postoperative complications and multiple side effects, especially in surface tumours such as oral squamous cell carcinoma (OSCC). In this study, we developed a microwave cold atmospheric plasma (CAP) device in conjunction with tumour microenvironment-responsive nanohydroxyapatite (nHA) for the first time. The synergistic effects of CAP and nHA combined application on OSCC were evaluated in both in vitro and in vivo experiments. The synergistic effects of CAP and pH-responsive NH2-nHA on the apoptosis, intracellular reactive oxygen species (ROS) and calcium ion concentration of OSCC cells were investigated in vitro. The synergistic induction of CAP with NH2-nHA exhibited optimal tumour-specific inhibitory effects on OSCC. The results revealed that the combined application of CAP with NH2-nHA induced apoptosis of tumour cells in vitro and killed 84.0% of tumours in vivo. Mechanistically, CAP enhances extracellular ROS production, while NH2-nHA amplifies intracellular calcium ion (Ca2+) concentrations, synergistically increasing intracellular ROS levels to provoke oxidative stress in OSCC cells, ultimately triggering the mitochondrial apoptosis pathway. In conclusion, the combined utilisation of CAP and NH2-nHA presents a promising avenue as a novel, selective, and non-invasive strategy in the management of OSCC.
